A CSS gradient is a function-driven background, not a bitmap asset
A gradient generator helps turn design intent into reusable CSS. Instead of editing pixels, you define a direction and a sequence of color stops, then let the browser interpolate the transition. This is useful for hero backgrounds, call-to-action surfaces, overlays, cards, and any interface element that benefits from controlled color progression without extra image files.
This tool expects a linear-gradient direction followed by at least two color stops
The first input line is treated as the gradient direction, such as `90deg` or `to right`. Every following non-empty line is treated as a color stop. The tool validates the stop values, then generates a `background: linear-gradient(...)` declaration together with a preview class snippet. Because the implementation targets `linear-gradient()`, radial or conic gradients are outside its current scope.
Key parts of a gradient declaration
| Part | Role |
|---|---|
| Direction | Controls the visual flow of the color transition. |
| Color stops | Define the start, intermediate, and end colors of the gradient. |
| Generated CSS | Lets the same gradient be reused consistently across components. |
Scope Note
If the design requires radial or conic gradients, or precise stop percentages for complex art direction, review the generated CSS manually before publishing.
このツールの使い方
- Prepare representative CSS gradient direction, color stops, positions, and preview colors in CSS グラデーション生成 instead of starting with the largest or most sensitive real input.
- Run the workflow, generate copyable CSS gradient syntax, and review color contrast, stop order, browser support, banding, and readability of text placed on the gradient before deciding the result is ready.
- Only copy or download the result after it fits button states, section backgrounds, design tokens, prototypes, and quick CSS handoff and no longer conflicts with this constraint: Check gradients with real foreground content because a good-looking swatch can still fail contrast requirements.

FAQ
CSS グラデーション生成 の用途と、入力・出力・結果に関するよくある疑問をまとめています。方向と色ストップから linear-gradient CSS を生成します。
What kind of CSS gradient direction, color stops, positions, and preview colors is CSS グラデーション生成 best suited for?
CSS グラデーション生成 is built to build a linear-gradient declaration visually. It is most useful when CSS gradient direction, color stops, positions, and preview colors must become copyable CSS gradient syntax for button states, section backgrounds, design tokens, prototypes, and quick CSS handoff.
What should I review in the copyable CSS gradient syntax before I reuse it?
Review color contrast, stop order, browser support, banding, and readability of text placed on the gradient first. Those details are the fastest way to tell whether the result is actually ready for downstream reuse.
Where does the copyable CSS gradient syntax from CSS グラデーション生成 usually go next?
A typical next step is button states, section backgrounds, design tokens, prototypes, and quick CSS handoff. The output is written to be reused there directly instead of acting like a generic placeholder.
When should I stop and manually double-check the result from CSS グラデーション生成?
Check gradients with real foreground content because a good-looking swatch can still fail contrast requirements.
